ServerComm

This item only works when running on the server. Server

Types​

ServerMiddlewareFn​

</>
type ServerMiddlewareFn = (
player: Player,
args: {any}
) → (
shouldContinue: boolean,
...: any
)

The middleware function takes the client player and the arguments (as a table array), and should return true|false to indicate if the process should continue.

If returning false, the optional varargs after the false are used as the new return values to whatever was calling the middleware.

ServerMiddleware​

</>
type ServerMiddleware = {ServerMiddlewareFn}

Array of middleware functions.

Functions​

new​

</>
ServerComm.new(
parent: Instance,
namespace: string?
) → ServerComm

Constructs a ServerComm object. The namespace parameter is used in cases where more than one ServerComm object may be bound to the same object. Otherwise, a default namespace is used. 

local serverComm = ServerComm.new(game:GetService("ReplicatedStorage"))

-- If many might exist in the given parent, use a unique namespace:
local serverComm = ServerComm.new(game:GetService("ReplicatedStorage"), "MyNamespace")

BindFunction​

</>
ServerComm:BindFunction(
name: string,
fn: (
player: Player,
...: any
) → ...: any,
inboundMiddleware: ServerMiddleware?,
outboundMiddleware: ServerMiddleware?
) → RemoteFunction

Creates a RemoteFunction and binds the given function to it. Inbound and outbound middleware can be applied if desired. 

local function GetSomething(player: Player)
	return "Something"
end

serverComm:BindFunction("GetSomething", GetSomething)

WrapMethod​

</>
ServerComm:WrapMethod(
tbl: table,
name: string,
inboundMiddleware: ServerMiddleware?,
outboundMiddleware: ServerMiddleware?
) → RemoteFunction

Binds a function to a table method. The name must match the name of the method in the table. The same name will be used on the client to access the given function. 

local MyObject = {
	_Data = 10,
}

function MyObject:GetData(player: Player)
	return self._Data
end

serverComm:WrapMethod(MyObject, "GetData")

CreateSignal​

</>
ServerComm:CreateSignal(
name: string,
inboundMiddleware: ServerMiddleware?,
outboundMiddleware: ServerMiddleware?
) → RemoteSignal

Creates a signal that can be used to fire data to the clients or receive data from the clients. 

local mySignal = serverComm:CreateSignal("MySignal")

-- Examples of firing in different ways (see docs for RemoteSignal for further info):
mySignal:Fire(somePlayer, "Hello world")
mySignal:FireAll("Hi there")
mySignal:FireExcept(somePlayer, "Hello everyone except " .. somePlayer.Name)
mySignal:FireFilter(function(player) return player.Team == someCoolTeam end, "Hello cool team")

-- Example of listening for clients to send data:
mySignal:Connect(function(player, message)
	print("Got a message from " .. player.Name .. ":", message)
end)

CreateProperty​

</>
ServerComm:CreateProperty(
name: string,
initialValue: any,
inboundMiddleware: ServerMiddleware?,
outboundMiddleware: ServerMiddleware?
) → RemoteProperty

Create a property object which will replicate its property value to the clients. Optionally, specific clients can be targeted with different property values. 

local comm = Comm.ServerComm.new(game:GetService("ReplicatedStorage"))

local mapInfo = comm:CreateProperty("MapInfo", {
	MapName = "TheAwesomeMap",
	MapDuration = 60,
})

-- Change the data:
mapInfo:Set({
	MapName = "AnotherMap",
	MapDuration = 30,
})

-- Change the data for one player:
mapInfo:SetFor(somePlayer, {
	MapName = "ASpecialMapForYou",
	MapDuration = 90,
})

-- Change data based on a predicate function:
mapInfo:SetFilter(function(player)
	return player.Team == game.Teams.SomeSpecialTeam
end, {
	MapName = "TeamMap",
	MapDuration = 20,
})

Destroy​

</>
ServerComm:Destroy() → ()

Destroy the ServerComm object.
